Coupling agents for polyolefins reinforcement of natural fibers and compositions thereof.

摘要

A coupling agent for wetting a natural fiber comprising: a polyolefin resin combined with 1.6 to 4.0 weight percent maleic anhydride, said coupling agent having less than 1,500 ppm of free maleic anhydride; wherein said coupling agent has a melt index of 0.1 to 500 (g / 10 min) at 190 ° C and 2.16 kg; and wherein said coupling agent has a yellowness index of 20 to 70.
